Description
Technical field
The utility model belongs to the reverser technical field in the linear guide pairs, especially relates to a kind of for the oil storage self-lubricating type back assembly on the linear rail.
Background technique
The industries such as domestic high-end digital process lathe manufacturing, wide cut printing press machinery, mechanical, the extraordinary building materials abrasive machine of engraving machine.A large amount of such straight-line motion mechanisms of linear guide pairs that use in many automatic processing machine tools.The linear guide pairs reverser, by raceway, steel ball, fixing threaded hole, the compositions such as backhaul reverser.When guide rail and slide block were made linear relative movement, steel ball is the rolling path rolling on the guide rail just, and the steel ball in the slide block enters backhaul hole raceway by the backhaul device, and steel ball renews straight-line rolling as Zhou Er.In the prior art, reverser is made with nylon and plastic materials, and when this reverser operated under the rolling steel balls of carrying heavy load and the operating mode with lubricant oil, defibrator process wiping, reverser easily was out of shape, weares and teares; Very easily cause rolling steel balls retardance, knock against each other, have some setbacks, the phenomenon that noise is large.Affect the whole straight line moving-mass of guiding pairs product.
The problem that exists in order to solve prior art, people have carried out long-term exploration, have proposed various solutions.For example, Chinese patent literature discloses a kind of roller straight-line guiding rail assistant cannula return unit [application number: 200720018961.0], form separately composite structure independently of " split criss-crossing " two tracks by two intubate up and down, intubate has the L-type of raceway in being, there is the round end with slide block roller port hole location the intubate termination, there is the groove of circumferential location the round end end, lower intubate interior edge face has the boss with slide block end face location, there is the opening slot that holds lower intubate width and thickness upper intubate inboard, and there is the opening that communicates with raceway in the upper intubate outside.
Such scheme has improved prior art to a certain extent, but this scheme at steel ball rolling when raceway comprises in the load gravity operating mode, because from not moistening structure, between steel ball and the raceway or stuck phenomenon can occur; Secondly, this structure is fragile, is difficult for being used more widely.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of design more reasonable, and friction factor is little, and the oil storage performance is high, high lubricating effect, long service life be used for oil storage self-lubricating type back assembly on the linear rail.
For achieving the above object, the utility model has adopted following technical proposal: this is used for the oil storage self-lubricating type back assembly on the linear rail, be arranged on the guide rail, be provided with slide block at guide rail, this assembly comprises the retainer that is arranged on the slide block two ends, be provided with some road annular backhaul raceways at retainer, some rollers are arranged in the annular backhaul raceway, it is characterized in that, described retainer is provided with can make the certainly profit structure that forms oil film between described roller and the annular backhaul raceway surface of contact when the relatively annular backhaul rolling path rolling of roller.
At the above-mentioned oil storage self-lubricating type back assembly that is used on the linear rail, describedly comprise the some oil storage micropores that are arranged on the retainer from moistening structure.
Be used for oil storage self-lubricating type back assembly on the linear rail at this, soak into whole back assembly with lubricant oil first, when being in off working state, lubricant oil is filled in the oil storage micropore on the retainer; When in running order (comprising load condition), because of the rolling friction adstante febre, the retainer thermal expansion reduces the oil storage micropore, and the lubricant oil of oil storage nanopores on the retainer is overflowed, enter the surface of contact between annular backhaul raceway and the roller, roller is wrapped in the oil film.This structure has reduced the friction between roller and the annular backhaul raceway, high lubricating effect.After roller stops to roll, roller and retainer cooling, the oil storage micropore recovers, and lubricant oil is sucked back oil storage micropore again, high lubricating effect, long service life.
At the above-mentioned oil storage self-lubricating type back assembly that is used on the linear rail, described retainer comprises the reverser that is arranged on the slide block two ends, each reverser is provided with the reverser lid near slide block one end, described annular backhaul raceway comprises and is arranged on the backhaul groove that the cross section on the reverser takes the shape of the letter U, cover at reverser and to be provided with the spacer block that described backhaul groove interval can be formed described annular backhaul raceway, the oil storage micropore is located at reverser respectively and reverser covers.
At the above-mentioned oil storage self-lubricating type back assembly that is used on the linear rail, described reverser and reverser lid are made by copper based powder metallurgy material die casting.Certainly, mechanical property requires and material with oil storage function all can use as long as the material here can satisfy.
At the above-mentioned oil storage self-lubricating type back assembly that is used on the linear rail, this assembly also comprises and is arranged on each reverser away from the baffle plate of slide block one end, is provided with some clamping bolts at baffle plate, and described bolt-through retainer is located on the described slide block.Structural strength is high, and is fixed.
At the above-mentioned oil storage self-lubricating type back assembly that is used on the linear rail, one of them baffle plate also is equipped with lubricating cup away from reverser one end.
Compared with prior art, this advantage that is used for the oil storage self-lubricating type back assembly on the linear rail is: 1, design is more reasonable.2, when being in off working state, lubricant oil is filled in the oil storage micropore on the retainer; When in running order (comprising load condition), because of the rolling friction adstante febre, the retainer thermal expansion reduces the oil storage micropore, and the lubricant oil of oil storage nanopores on the retainer is overflowed, enter the surface of contact between annular backhaul raceway and the roller, roller is wrapped in the oil film.This structure has reduced the friction between roller and the annular backhaul raceway, high lubricating effect.After roller stops to roll, roller and retainer cooling, the oil storage micropore recovers, and lubricant oil is sucked back oil storage micropore again, high lubricating effect, long service life.3, structural strength is high, and is fixed.4, long service life.
